Drew and Dalton Knapp will compete on tonight’s episode of “American Ninja Warrior” at 7 p.m. on NBC.

The brothers made the cut for Season 10 of the extreme obstacle course competition. It’s the third consecutive season for Drew, who made it as far as the national finals on Season 9 of “ANW” last September. His younger brother, Dalton, advanced to the Denver finals the same season.

In May, the Knapps went to U.S. Bank Stadium in Minneapolis to tape for the current season. Minneapolis was one of six cities to host regional qualifying and finals rounds.

The inspiring story of the two men, both Bay Port High School graduates, is now a familiar one to "ANW" viewers. Dalton was diagnosed with Burkitt leukemia at age 10 in 2006, and training with his brother on their family's backyard obstacle course helped him get his strength back.

In 2016, Drew competed in his brother's honor with the slogan "Can't Stop Knapp." Last year, Dalton, who has been in remission for 10 years, also made the cut for the show. The brothers have said it was a dream come true to be able to compete on “ANW” together in 2017.
